-LRB- CNN -RRB- -- The trial of Olympic sprinter Oscar Pistorius , charged with murder in the death of his girlfriend Reeva Steenkamp , will begin in March 2014 , his attorney Kenny Oldwage told CNN on Sunday .

The first phase will take place in March , but the entire trial could take place at various times across a year or more due to potential motions and postponements along the way .

Pistorius will be served with an indictment Monday following the completion of the investigation . It 's the day that would have been Steenkamp 's 30th birthday .

Pistorius is charged with premeditated murder over the February shooting death .

The double amputee track star killed the woman he calls the love of his life on Valentine 's Day in his home . He says he mistook her for a home invader .

The police investigation team `` is convinced that the accused has a charge to answer , '' a police statement said .

The athlete 's family said in June that he would resume running using his blade-shaped prosthetic legs .

Pistorius has started sprinting again for the sake of his emotional health , not for training to compete again , the family said .
